Has anyone found the following behavior in RichTextBox?  When you set L.
Margin and then place cursor in the box and use mouse to highlight it if you
hit enter
or any other key the margin disappears and everthing on that line is left
justified no margin.

I heard that the guts of RichTextBox were based on WordPad technology but
this doesn't occur in WordPad.  Any suggestions or work arounds?  Thanks in
advance.
